HERBERT E. BRIDGWATER, OF SYRACUSE, NEW YOR ASSIGNOR TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPEWRITING MACHINE.

Application med January s1, 1222. seria No. 532,953."

T all whom it may concern.'

Be it known that I, HERBERT E. BRIDG- wArnn, citizen of the United States, and resident of Syracuse, in the county of @nondaga` and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the followingr is a specification.

VMy present invention relates to typewriting machines and more particularly to what are known as collapsible or portable typewriters and to the type actions thereof. The main object of the invention is to provide new and improved type bar actuating mechanisin and .which is especially acapted for employment in a collapsible or portable typewriter wherein the type bars are collapsible.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointedout in the claims.

In the accompanying drawings which illustrate the preferred form of my invention,

Fig. 1 is a fragmentary top plan view of a portable or collapsible typewriting` machine embodying my invention, only so much of the machine beingshown as is necessary Vto a complete understanding of the invention.

Fig. 2 is a fragmentary vertical sectional view taken on a plane indicated by the section line 1-1 in Fig. 1 and looking in the direction of the arrows at said line, said Fig. 2 showing a type bar in compacted or lowered position however, whereas Fig. 1 shows the type bars raised for use.

Fig.` 3 is a view corresponding to Fig. 2 but showing the type bar expanded or raised into position for use as in Fig. 1.

Fig. 4 is a fragmentary sectional view showing the type bar action of Fig. 3 in operated position, the lower case tjpe being shown in printing contact with the platen.

Fig. 5 is a fragmentary transverse vertical sectional view taken ona plane indicated by the section line 2 2 in Fig. 1 'and looking:r rearward in the direction of the arrows at said line. v

The main frame of the machine comprises as clearly appears from Figs. l and 2', parallel vertical side plates or members providedV at their front ends with inturned ears 2 to which are securedby screws 3 a cross niember or comb platedwhich guides the 'printing key-levers of the machine. The main frame further comprises a top plate 'suitably secured to certain of the frame mem-l bers. Suitably supported on the main frame is a traveling platen carriage (not shown) on which is mounted rotary platen 6 diagrammatically illu grated. The carriage may be and preferably is constructed and mount.

and other mechanisms, vall of the character found in sail Remington-portable machine.

In carrying out my invention in the present instance I provide a type bar support which is shiftably mounted for the purpose of enabling' theitype bar system to be alternately expanded for use, and compacted when in disuse to reduce the dimensions of the machine for convenient handling;V or boxing. Said type har supportis in the form preferably of a horizontally disposed segmental body 7 provided with lateral wings 8 cast integrally with the l, dy and terminating` in upright depending; extensions or slide bars 9 formed along` their outer faces with vertical V-grooves 10 (Figs. 1, 2 and 5). Oppositely facing co-operating' V-grooves or seats 11 are formed in the stationary trackbars 12. The opposing grooves or seats receive sets of rollers or balls 13 which are preferably associated with ordinary separators or controllers,roller bearings thus being provided for the support or segment 7, V8, 9. The track-bars 12 are preferably in the Vform Vof steel inserts which are firedly setin rectangular grooves or depressions, indicated at 14, formed 1n upright track-bar holders 15.. These track-bar holders form an 1nteeral nart of a' casting or frame nece b L t1 webs 11T which connect the holders or bars l5 and their' vfixed tracks l2 to the body 16.V T ie outer iaces et the upright bars l are 'formed with bosses .ltl threaded to receive. headed screws 19 which rigidly secure the casting or member l5, 1G and the side 'frames l toA gether, thus constituting' said ineniber a. part ot the inain traine on which the seg'- ent i', 8 is niovably mounted by means ot the ball bearings. rfhese aiiord free upand-down movement ot said segment while t the saine time niaintaininothe segment at ll tinies in proper relationship to 'the inain r'irne. rlie upporinchued tace ot the 1 f l) ias secured to it at itsr middle, by headed is inclined upward and rearward and tcrniinates in a ,cuide opening', indicatedV at Q2,

with which. tlietype ends or the type bars are adapted to co-operate as they near the vprintingT point on the top of the platen. Said type bars, cach de ignated by the reierence numeral Q3, are arranged in an are oi a circle forward ot the platen, being' received in vertical slots indicated at 2li tornied radially in the front and under portion ot the segment 7, these -guide slots ating' 'troni a common center on the type guide 2l at the lower end of the guide open- 22. For the sake ot convenience, only' a tcw o't' the guide slots or lers are illustrated in the drawings l, 2 and f3), but it is to be unde stood that the segment 7 is cut or formed with a lull series ot such slots il"- cient to receive and guide a complete set et type bars rlhese type bars are mounted ou a common arcuate pivot wire 25 which is received and housed in a slot Lformed horizontally in the upper' portion ot the segment and indicated by the numeral 2G. The

radit tree end of each type bar is provided with a type block 2l' havingtwo types, one lower case and one upper case. At the under side ot the type bar opposite the type block is a rounded projection or nose 28 which, when the machine is compacted (as in Figi'. 2) may contact with the top plate 5 or preferably with a pad 2' ot compressed felt or the like which is secured in a slight countersinlr or depression in the top plate, said pad being arcuate and extending from one side ot the top plate to the other near its front edge which may be rounded to provide a suitable finish. At this time when the machine is compacted and the type bars are in disuso their body portions are recunibent or substantially horizontally disposed, and, at a slight distance Jforward ot their pivotal support 25, rest on and are supported at their undersides by fixed means, which, in the present instance, is in the form ot' an arcuate wire inernber or pillow 30 which is suitably screws 20, a center guide ineinber 2l which` tion ot the top plate 5. The

sta-

the rear edge t, inernoer or rest 30 is hired or as contrasted with the siiiiitablc rest pme, and the rear upper side of said restshifted ni'ayslide freely over and upon said rest. 'lf he heel portions or those portions of Vthe ty lc bars at the opposite sides ot their l ulcru ns troni the bod;v portions, curve or extend downward when the type bars are in disuse, saidiheel portions passing' tirough the slots 2l. The heel oi" each type bar is l with a cern or curved actua-tin slot it Co-operatively engaging i i said slot is a headed actuating' pin 33 which projects laterally troni the rear end ot an operating; member or sub-lever 315i, said lever underlying' the associate type bar and haring a yielding or floating' support which is one of the important features of the present invention and will hereinafter be described in cetail. The sub-levers are left the lirst order and at their forward ends are iirotally conne/'ted at with the upper ends otdepeiidingf links 36, the lower ends of said' links being' pivotally connected at 37 with printing lrey levers The pivotal connections 37 are in the ilorrn of pins projecting" 1frein thev sides of the key lei-fers, the links 3G being' perforated 'to at bar 1G.- 'llhe iorward side ot said bar istorined with a series ot. pe. 'allel guide slots or kerts indicated at l2 in which the rear or pivoted portions ofthe hey loyers 38 are received and gruided. idear their tront ends said lrey levers pass through and are guided by the conib pla-te 4, said ley levers terinif natingg in upright portions or sterns 38 which receive finger Vkeys or buttons The steins of the lrey levers are varied in height so as to provide rows or banks ot diiiqerent heights vas is usual, there being tour banks or lreys in the present case. Preferably, the keyboard is enclosed in a U-shaped traine piece, not shown herein, but which may have rearwardly extending; sides which are suitably attached to the main 'trame of the inachine.

The type bars 23 are adapted to slide over the rest 30 in order to be elevated into a position for use, this being accomplished by shitting the seen'ient or type bar support downward. With the type bars having a pinandslot or direct connection with their sub-levers 34 it was foundV to benecessary in order to enable the type bar-'support to be freely shifted to expand the machine :tor use,V to provide a yielding fulcrum or support for the sub-levers. In the present instance this support is aorded'by individual iulcrum arms 44, one for each sub-lever 34. The tulcrum arms are substantially upright when the machine fis in' collapsed condition, each fulcrum arm being provided at its upper end with an open-mouthed slot indicated :at 45 which receives a'headed fulcrum pin 46 projecting laterally from the side of the associate operating lever 34 between its ends and resting in the bottom of the slot, there heiner thus provided a iulcrum for the lever 34. Thefulcrum arms 44 are pivotally supported at their lowerends on an arcuate pivot Wirel 47 common to all of the fulcrum arms, and mounted in turn on a support 48 which is horizontally disposed forward oiz the typebar segment and is segmental in shape, being of considerably greater radius than the type bar segment, so that the two supports or segments may in a sense be interseated. The segmental support 48 may be an aluminum casting provided with in tegral lateral extensions 49 which are angularly disposed, as clearly appears from Fig. 1, the outer faces of said extensions being flattened to fit between the side plates 1 with which they are held in fixed and rigid relationship as by headed screws 50. The lower ends of the fuleriim arms 44 are received in and guided by slots or keri's indicated at 5l formed in the rear portion ot the segment 48, these guide slotsl beingr radially formed and having the `same center as the slots 24 in the segment?, the two sets of slots being inline with each other as clearlyV appears from Fig. l. It is to befunderstood that while for convenience of illustration the full showing ot the slots 5l has been omitted from the drawings, yet there is a complete series of said slots extending from one end to the Vother of the segment 48 which supports the sub-levers 34 and their tuicrum arms 44, said slots 51 corresponding in number to the slots 24 in the type bar segment 7. It will be seen that the type bars together with part ot' their type actions comprisingr the levers 34 radiate from a common ceiter` while the key levers extend foreandatt ot the machine in substantial `parallelism although slightly tanned outward at the sides of the system in order properly to space the keys inthe keyboard. Also it will be apparent that the links 36 may be bent or twisted in order properly to connect the sublevers 34 with their key levers 38. Each type action is provided with spring restoring means which may vcomprise a coiled ,spring hooked at its upper end through a hole in the associate Vsub-lever 34 back oi downward 'and beine anchored at its lower` end to a spring'plate 53. Said plateis suitably vsecured tothe underiace otl the seg-l nient48 and is arcuate in shape, the inner edge at 54 being inclined upward and rearward and being'tormed with a' series ot holes through which the 'lowereends of the springs 52 are hooked. VThey upper tace ot the segment -48 has suitably secured to it-a` hori- Zontal plate which is also arcuate in shape and is .inclined upward at its inner ledfgge as shown at 5G, the iace ot this inclined'portion 56 'providing a rest or support for the sublevers when the machine is in lise, said sub-levers`havingj movements which may be said to be nioi'eor less tore-andfaitt or horizontalA during thc expansion and compaction of the machine as distinguished Yfrom the vertical shitting; movements oi the type bar segment or support 7. The 'forwardV edge portion oi' the plate 55 is adapted to serve as a locking device, preventing` operation ot the type actions when depressed as in Fifi. 2, a shoulder or hooi; 36a with which each link is lprovided contacting atl this time with the plate so as to prevent downward movement of the link under actuation ot the associate key lever.

Hand operatedmeans are provided 'for shifting the type har support vertically in i 's bearings in order 'to compact the type hars and to raise or elevate them 'for use, said means comprising a rock sha t 57 arranged transversely 0i the machine in its base, and bearingF at the ends ins 'table openings in the side plates i.. A pair et crank arms 5S are mounted on the rock shaft 57, one being# arranged near each end ot the shaft inside the neighboring side plate l. Each crank arm 5S is provided with a collar 59 which rreceives a cross pin 60 whereby thefcrank arm is fixed to the shaft. T he outer end of each crank arm is pivotally connected as by a headed and shouldered rivet 6l with one end ot a. link 62, the opposite end ot said link bearingon the shouldered portion ot a screw 63 ywhich is threaded into a lug; 9 projecting forward from the associate eX- tensions 9 on the ltype bar segment 7, 8. Said segment is thns connected. at each end with the rock shatt 57 by trains of devices which are in etiecttoggles, each toggle. comrprisine: two elenients, viz., a link 62 and arm which are pivotally connected together at Gl, to provide a toggle-joint which be opened or straightened also partiallyV 1 andv the collar hearing' therein. A. headed screw 65 three l .den into the ieithand end of the shaft 57 cooperates with the outer face of the left-hand end plate 1 to preventwhich houses a poppet stud and also sup-V ports 'a convenient finger piece (Figs. 1 and 5) The housing 66 is bored out as indicated at 67 to receive the poppetstud or pin 68 which is provided with a` flange 69 and carries outside the housing 66a cap 70 which lits over the end ot the housing and affords means for pulling the poppct stud longitudinally outward against the force oit its spring and also for adjusting the crank arm 64. Said spring 71 is coiled around the stem of the stud and is confined between the bottom of the housing 66 and the flange 69'. The inner end of the stud is adapted to co operate with two holes 72 formed in the right-hand side plate 1, one hole located to lock thecrank arm 64, the toggles 58, 62 and the type bar segment 7 8 all in the position illustrated in Fig. 2 where the toggles are straightened, the segment is raised and the type bars lowered or compacted, the other hole 72 co-o-nerating to lock the parts in the positions illustrated in Figs. 1, 3 and 5 where the toggles are broken, the type bar segment is lowered and the type bars raised in position for use. Excessive downward movement of the segment 7 8 is prevented by angular stop pieces 73 which are secured at their outer ends by screws 74 to the bottom of the tra-ck bars 15, the lower end portions o't said stop. pieces projecting into the path ot the slide bars 9. the bottoms of said slide. bars being adapted to contact with and rest on said stop pieces or plates 7 3 as shown in Figs. 3 and 5. In Fig. 2 the typewriting machine is shown in collapsed or compacted position at which time it will be observed the bodies of the type bars are recumbent or supine, being substantially horizont-ally disposed'and in contact at their forward ends with the pad or plate. 5. Just forward of said pivots the bot-tom edges of the bars rest on the rest 30 which is substantially in the horizontal plane of the top or printing face ot the platen, the pivots of the type bars being at this time close to said plane. The toggle elements 53 and 62 are substantially straight so that the weight ot' the type bar segment is largely sustained by the toggles and the rock shaft 57. Also at this time the fulcrum arms 44 are substantially upright.

llVhen it is desired to `e\pand the machine tor use the poppet or locking pin 68 is first withdrawn from the rear hole'72, leaving the crank arm 64 tree to be swung forward until the poppet 68 is brought opposite the forward hole 72 and locked therein. This forward movement of the crank arm. rocks the shaft 57 and breaks the toggles 58, 62, swinging the toggle elements into the angular relationship shown in YF ig. 3 and causing the segment to'be shifted or lowered vertically downward on the tr'aokways 12 to its lower positionwhere it is supported by the stop plates 7 3. This shitting movement in the present instance isv about three-quarters ot an inch'in length.

i As a result the shi ted segment 7 is brought over the stationary rest 30 and as he iul- Crum wire 25 moves downward belowsaid rest the bars will swing Vpivotally on said wire, changing their angular relationship with the segment and being raised or elevated at their type ends to the position shown in Fig. 3. From this ligure it will be observed that while the combined bodily and pivotal movement ofthe type bars has not brought them to an exactly vertical position yet lthey are substantially upright and arcsupported by the rest 30 above their pivots in position to be actuated to print when their key levers are depress-ed. f The raising or elevation oi the type bars from compacted to expanded position by moving or slidingv over their stationary rest is permitted by reason of the fact that the tulcrums of the levers 34 are floating or yieldingly mountcd'so that the levers may all simultaneously move or yield to fthe shitting ot the type bars, these movements carrying the said levers from the Fig. :3 position' radially outward to the FigaV 3 position. The levers 34 near the middle of the machine will have a substantially for# ward movement. `While the motions or" the outer levers ol5 the series will include lateral or sidewisc components, still to a considerable extent their movement is also forward. The ulcrums 46 of the sub-levers or levers 34 also move forward, and at the same time are slightly lowered due to the fact that the fulcrum 'arms 44 swing downward from the upright position to the inclined position illustratedY in Fig. 3. This forward movement of the sub-levers swings the upper end portions ot the links 36 forward Vabout their pivotal connections 37, which latter remain stationary,and this swinging'movement ot the links clears the locking shoulders 36 from the locking plate'55, thus` unlocking the type actions so that they may be readilvcperated by depression of th printing keys 43.

Then one of the lprinting key' levers is depressed the parts or' the type action willV type bar be swung from `the Fig. 3 position to the position illustrated in Fig. 4, the link 36 pulling down the forward arm of the sublever 34 and raising the rear arinthereof,

causing the .actuating pin 35 on saidarm t0 traverse the cani slot 32 and swing the type bar downward with an accelerating motion duc to the relationship of the pinandslot connection between the type bar lthe platen alt-*this` time being in its forward or lower case position, theinner or lower" case type on the actuated type bar `will co- It will be understood that when it is desired to print in upper casetlie platenis shifted rearward to the dotted line position o' Fig. 4 `and that this case shitting movement of the platen is entirely distinct from and bears n0 direct relationship to the shitting;4

movement oi' the type bar segment for coinpacting and expanding the machine. It will further be noted that during the printing actuation of the type bar the bodily location of the ulcruin'of the sub-lever will not be disturbed, the fulcruin arm remaining in contact with the rest or stop 5G. On releasing the actuated printing key the parts will be restored to normal-position by the action of the restoring spring- 52.

The machine is compacted or vcompressed and the type bars simultaneously restored from the position of use (Fig. 3) to the position of disuse (Fig. by manipulating the'crank arm 64, swinging` it back to its rearinost position, straighteningF the toggles, raising the type bar segment and causing the type bars to slide or move over their stationary or fixed rest from the 3 to the Fig. 2 position.
